A cross-flow radiator is often the best setup, but a down-flow aluminum one would fit better in my truck since the space is taller than it is wide. This 3-inch dual-row unit is designed for a Ford Mustang (adding to the montage of make/model parts in this truck) and measures 26 inches wide by 20 inches tall. Since I didn't need an integrated transmission cooler, steering cooler, oil cooler, or electric fans, it made for a much easier install, but Be Cool can deal with all those needs if your truck has them.
